PB-4333N-1

Overview

The Soberton Inc. PB-4333N-1 is an internally driven piezoelectric buzzer designed for panel mounting applications. It operates at a rated voltage of 24 V with a current consumption of 20 mA. The device generates an acoustic signal at a resonant frequency of 2.9 kHz, achieving a sound pressure level of 90 dB measured at 30 cm. Key physical characteristics include screw terminal termination and a diameter of 43 mm. This component integrates the drive circuitry within the housing, allowing for direct connection to control signals without external drivers.

Feature Summary

• Internally driven piezoelectric technology eliminates the need for external driver circuits
• Panel mount design with screw terminal connections for secure installation
• High acoustic output capability suitable for industrial alerting environments

Applications

• Industrial automation machinery status indicators
• Commercial appliance alarm systems
• Security system sirens and warning devices

Procurement Notes

Verify that the required operating voltage matches the 24 V rating to prevent damage or insufficient performance. Confirm that the mounting interface supports the specified screw terminal type. Ensure the application environment does not require washable components, as this model is not washable. Check spatial constraints against the 43 mm diameter dimension.

Selection Notes

Select this component when an integrated solution is preferred over externally driven buzzers to simplify PCB layout. Consider the 90 dB output level for environments requiring high audibility. Evaluate the 2.9 kHz frequency for specific auditory alert requirements. Compare dimensions against available panel space before finalizing the design.

Part Context

This part belongs to the PB series of piezoelectric buzzers from Soberton Inc., which focuses on indicator and alarm solutions. The series offers various voltage ratings and mounting options. The PB-4333N-1 specifically targets higher voltage applications compared to lower voltage counterparts in the lineup.

Replacement Considerations

Direct substitutes must match the 24 V rating, 2.9 kHz frequency, and screw terminal mounting style. Verify dimensional compatibility with existing panel cutouts. Ensure the replacement maintains the internally driven feature if external driver space is limited.
